I currently own a Thommaso Augusta Track bike, and im looking for a new frame. I hate the geometry of my bike; the top tube slopes from the head tube, to the seat tube. Im looking for a flat toptube if possible.
All i can find is leader frames which appear to have flat top tubes but im not sure.

And im also looking for a low pro, the only brands i know are , Affinity, Geekhouse, and Spicer. I know they are hard to come by and really expensive, but am i missing a cheap low pro?






Thanks for the help!

hmm where do yo live? there is a cheap pursuit frame on CL in Austin right now. Try emailing the guy and see if hell ship...it's kinda funky but here:

I live in Cali like 20 minutes from SF.

And i think conversion are icky. ahah

yeahhh I know it's an eyesore, but I figured I would just show it to you cause it is CHEAP and I just saw it earlier today.

looking for 700c rear and front, i dont like "funny bikes" with 650c fronttttt,


Thanks for helping though!

just do yourself a favor and order an affinity.

Yeah, now that i think about it, i would rather have a regular track frame, instead of low pro.

But i cant find any modern fixies size 56-59cm that have flat top tubes. i hate sloping tubes.


Im close to learning how to make frames, and building a bike for myself.

Where on earth did you look?

Canondale Capo
IRO Mark V
Bianchi Pista
Any of a dozen leader bikes
Surly Steamroller
Fuji Track
Kilo TT
Windsor The Hour

etc etc

I'll ship my Schwinn Prologue TT Pursuit... 600A front, bladed spokes to DA hub, tubular. Rear is a HED disc tubular with freewheel hub. You can convert it the axle, or not.

Pic? And whats 600a? Sorry, ive only heard of 650c, and 650b.

I'll take pics soon, probably tomorrow night or Friday. 600A is 24" (same as that Nishiki Funny Bike). 650 is 26" and 700 is 28" (roughly).

wow that's a rip off... I got my shogun kaze with full shimano 600 and original paint for 220... in cali.

and if anything i'd say the majority of track bikes have horizonal top tubes.

A Iro Mark V sounds like a good option for you.

From https://www.bicycletires.com/a_51/Tir...rt/article.htm

540mm 24x1 1/8, 24x1 3/8 (E5), 600A Commonly used on wheelchairs. Also used on British children's bikes.

Yes... 24" wheels actually have FOUR different ISO sizes as well.

Yeah, the IRO sounds good, but im thinking about a leader right now. Because they have flat top tubes, and i love fat downtubes. My best friend "is" getting one he says, but he also says alot of things. haha, so leader is at the top of my list

So what exactly are you looking for in a bike? Fat downtube,non-sloping top tube, and track ends.

Do you care at all about how it rides, or are you just going to hang some brightly-colored parts on it and call it a day?

Exactly, Fat downtube, non slopinng top tube, and track dropouts.

and i use my fixie for riding to school, 700cmx(tr1kz), and going on long rides with my friends. I have all stock parts from my Thommaso, and im not looking to get anything new.

I dont see what people mean when they ask if i want a bike that rides good? i just care if the saddle is comfy, and if i ****ed up my rear hub again.

the leader, and the bianchi pista concept are the only bikes i can think of with those three qualitys.
1.the leader is recycled through my friends(alot of leaders in my town)
2.bianchi pista concept is way to expensive, and extinct. i wouldnt be able to ride that thing hard, because i dont want to **** up the paint.

then get a pre beat up concept?

I mean, i can see keeping a bike nice looking and all, but I like to get it a little ****ed up first so I can enjoy it and not worry about chipping it on bike racks or dropping it by accident

So what you're saying is that you want to sell a bike with better geometry for what you want to do and buy a low quality frame that has poor geometry and a harsher ride just so you can have a flat top tube? The top tube on that thing has hardly any slope to it! Your bike also has very very similar geometry to the Pista.
